Taurus GX4 Micro-Compact 9mm Pistol: Concealment with High Capacity The all-new Taurus GX4 9mm pistol is designed to deliver maximum concealment without sacrificing ergonomics, performance or capacity for less than $400. May 19, 2021 By Guns & Ammo Staff The Taurus GX4 micro-compact 9mm pistol offers everything you would expect from a full-frame defensive handgun but at a fraction of the size and weight. The new Taurus GX4 redefines the micro-pistol segment to deliver the concealability of a .380 but with the power, capacity, and function of a full-size 9mm handgun. The Taurus GX4 is built on a stainless frame with a polymer grip that earns high marks in shooter comfort and strength. This thin, one-inch-wide frame provides negligible printing when worn inside the waistband and features a grip dimension sized to fit any hand. To ensure structural rigidity and reliable cycling in such a scaled-down foundation, the polymer receiver bolsters an integral stainless-steel framework that eliminates flex or deformation when firing.
